Do you rooted your phone and using rooted apps? I was having an issue with the battery consuming too much energy by the rooted apps. A factory reset fixed the issue in my case, you could try that as well.

No! I have not rooted my phone.
Well i was trying to root my phone through kingsroot app and after that this app added to the systems app.
But after upgrading my device to 6.0 It removes,so i don't think that it has effect on my device.
